Just curious, how many people use gmail. How many people haven't heard of it. If you do use it, do you like the single-folder inbox?
I am a huge fan of the entire system, so much so that I don't use anything else for my email. I've even given up the Apple Mail (yes, I know it can work with Gmail, I just like the web interface that much.
Ever since I first discovered MP3s in 1995-6 I have wished that everything had ID3 tags. Now with Flickr and Technorati and and iTunes and GMAIL, just about everything does.
